configure: make it possible to run one off command

It is now possible to run one off commands by specifying them as
positional arguments on the command line. The double-dash ('--') idiom
should be used to stop processing arguments by configure.py.

Example:

    ./configure -- python -O build.py
qt5-minimal-webkit: sort build flags by name
Cosmethic
Cosmethic
Rename util.py to sdk.py
Add docstring to chdir
chdir: wrap in try/finally block
